I have a Bradford White gas water heater. 5 years old. The power vent comes on, but the burner won’t light. I hear a click, but no flame. If I unplug for .5 hour and re-try, sometimes it will light.
Probebly the electric rod sensr by the burnr is dirty and need cleaned or new. If you played with these befor and didnt blow up, you can replace yourself.
